This document is a detailed and well-structured resource designed to help students and professionals master essential Excel functions for the Cambridge A-Level IT 9626 syllabus. Written by Chimwemwe Shaba, a Computer Science and ICT teacher, the guide provides clear explanations, practical examples, and expected outcomes for each function, making it an invaluable tool for learning and reference.

The guide is organized alphabetically, covering a wide range of functions from A to Z, including logical functions like IF, AND, and OR, lookup functions such as VLOOKUP, HLOOKUP, and XLOOKUP, statistical tools like SUMIFS, AVERAGEIFS, and COUNTIFS, text manipulation functions including CONCATENATE, LEFT, MID, and RIGHT, and date and time operations such as DATE, WEEKDAY, and YEAR.

A standout feature of this guide is its focus on practical application. Each function is accompanied by a real-world example, demonstrating how to write the formula and what result to expect.
